GREENSBORO — Wake Forest’s Aaron Rountree didn’t have a chance to break a sweat before his biggest contribution of the season.

Rountree drained a 3-pointer less than a minute after entering the game for the first time as part of a stretch that quelled Notre Dame’s second-half rally. It helped Wake Forest to an 81-69 victory against Notre Dame in the opening game of the ACC Tournament.

“As soon as it touched my hands, late shot clock. See, it wasn’t like I was hunting a shot. The shot clock was going down and I was like, ‘This is the best shot for our team,’ ” Rountree said.

The shot, from in front of the Demon Deacons’ bench, swished home from the sophomore forward, who had made two 3s in 31 games before Wednesday.

It came after Coron Williams drained four 3s in the first 22 minutes and after Miles Overton hit a pair of 3s in a rapid-fire burst.

“If you would have told somebody that trio, with me being the third one instead of Travis (McKie) hitting a 3, nobody would have believed you,” Rountree said with a laugh.

Not even your parents?

“My mom and dad probably wouldn’t have believed it,” Rountree said.

Notre Dame had whittled the Demon Deacons’ lead to 44-39 with 14:18 left after Wake Forest had led by 13 late in the first half.

That’s when Overton drilled a couple of 3s separated by 54 seconds from the corner. It was the second time this year that the freshman could remember connecting on a pair of 3-pointers so rapidly, but he prefers to think of those in the ACC Tournament as the more important shots.

“Against Duke I did, but we lost so I don’t really count that too much,” Overton said, referring to the first meeting of the season with the Blue Devils. “This is the best game I think I’ve played.”

Overton averaged 2.7 points per game and hit 13 shots from 3-point range this season. He had eight points against Notre Dame.

Then came Rountree, who didn’t exactly step onto the court with instant offense as a priority.

“I went in there for defense because (Pat) Connaughton was getting hot, so I had to slow Connaughton down,” Rountree said. “The 3 probably helped me stay in a little bit longer than the defense helped me. I was just glad to play some minutes.”
